Devices to temporarily hold and manipulate puncturing tools



Feb. 17, 1959 N. JACKSON DEVICES TO TEMPORARILY HOLD AND MANIPULATEPUNCTURING TOOLS Filed March 20, 1957 United States Patent EVICES TOTEMPORARILY HOLD AND MANIPU- D LATE PUNCTURING TOOLS John N. Jackson,Port Burwell, Ontario, Canada Application March 20, 1957, Serial No.647,355 2 Claims. (Cl. 223--104) This invention relates to devices totemporarily hold and manipulate puncturing tools, and the object of theinvention is to provide a simple and sturdy tool that w1ll afford amplelateral support to a puncturing tool, such as a needle or a small-headednail, and so hold it against distortion or breakage while being pushed,through the medium of the device, through one or more thicknesses ofcontacting layers of such relatively tough matenal as duck, paper,canvas, and relatively thin sheets or layers of wood. A needle may bemanipulated through the medium of this device to sew together one ormore layers of thick and heavy cloth, or fasten together relatively thinsheets of tin, copper, zinc, or lead, as hereinafter more particularlyexplained.

Fig. 1 is a side elevation of the tool w1th the pressurebar in itslowest position in the tool chamber.

Fig. 2 is a longitudinal section through one side of the tool chambershowing the pressure bar partly withdrawn therefrom.

Fig. 3 is a longitudinal section through one side of the tool chambershowing a threaded needle therein partly pushed through two layers ofmaterial to be sewn together.

Fig. 4 is a cross section on the line 4-4, Fig. 3.

In the drawings, like characters of reference refer to the same parts.

the tool comprises a tubular tool chamber 2 provided in one sidethereof, through its lower end, with a slot 3 of any desired length.This slot must open through the lower end of the chamber 2, and lieparallel to the longitudinal axis of this chamber.

As shown in Fig. 3, the thread 9, carried by the needle 8, passes freelythrough the chamber 2 and out therefrom by means of the slot 3 formed inthe side of said chamber (see Fig. 3 of the drawings), during the sewingoperation, and as this slot, as shown in the drawings, extends throughcompletely the wall of the said chamber 2 at no time can it oifer anyresistance to interfere with the sewing operation as the thread or wirepasses therethrough.

The upper end of the chamber 2 is exteriorly provided with a ring 4through which slides the tool herein called a pressure-rod 5 into thechamber 2.

So that the pressure rod 5 may be easily grasped by the hand formanipulating, it is provided, in any suitable way, with a fixed fingergrip 6. Although not essential to the careful manipulation of the tool,the finger grip 6 is preferably provided with an extension 7 of smaller"ice diameter than that of the finger grip itself. If an extension isnot used the finger grip will contact the supporting ring 4 when thepressure rod 5 is fully moved into the chamber 2, and thereforeconfusion may arise in handling the tool because of the proximity ofthese elements 4 and 6, when they are brought together. To avoid anychance of confusion in the handling of this device the extension 7 ispreferably used.

This tool can be used to insert small fastening devices such as pins,needles, and small-headed nails, in many locations.

As shown in Fig. 3 a needle 8 is held in the tool chamber 2, andtherefore it will be understood how other small fastening devices willbe held in said chamber 2 for insertion in any given place.

Held in the eye of the needle 8 (Fig. 3) is a linen thread 9 (or astring, or even a metal wire of small diameter) which may be sewn intothe material it is desired to operate upon.

The thread carried by the needle 8 will extend through the longitudinalslot 3 formed longitudinally in one side of the chamber 2 which housesthe tool to be used.

In Fig. 3 are shown two layers of any suitable material 10, to be sewntogether.

The needle 8 is of course placed within the tool chamber 2 in theposition shown before the said chamber is placed and held by hand incontact with the material to be sewn. By depressing the pressure rod 5the needle is passed through the layers 11, and then by pulling on theprojecting end of the needle beyond these layers the first step in thesewing of these layers together is carried out. The next step is to turnthe work over and repeat the operation just described, and soalternately until the sewing operation is completed.

I claim:

, 1. A tool of the class described comprising a straight tube forming achamber of uniform diameter throughout its length, and provided with alongitudinal slot extending completely through the wall of said tube forthe major portion of its length and opening through one end of saidtube; a supporting ring fastened exteriorly to the other end of saidtube and having a passageway therethrough in alignment with thepassageway through said chamber; a straight pressure rod adapted to bemoved in sliding contact with the chamber and longitudinally thereof andthrough said supporting ring, and a finger grip fastened to the upperend of said pressure rod, said rod being longer than said tube and beingextendible through the outer end of said tube.

2. The tool as set forth in claim 1 characterized in that an extensionis provided on the under side of said finger grip of lesser diameterthan that of said finger grip and said supporting ring.
